The MNS type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is developed by our company with reference to and comprehensive improvement of ABB's MNS series low-voltage switchgear in Switzerland. It is currently one of the most advanced low-voltage withdrawable switchgears in China. This product is composed of standardized and serialized modules, and the drawer has a reliable mechanical interlock device, making it safer and more reliable for users.
The JP series low-voltage integrated power distribution device (hereinafter referred to as the integrated distribution box) is mainly suitable for AC 50Hz urban and rural power grids with a rated voltage of 0.4kV or lower. It is installed on the low-voltage side of 10/0.4KV outdoor transformers; it has multiple functions such as power distribution, power metering, data acquisition, voltage monitoring, overcurrent protection, phase-loss protection, low-voltage lightning protection, leakage protection, automatic reclosing after fault clearance, and reactive power compensation. This new outdoor low-voltage power distribution device is characterized by its small size, easy installation, anti-theft, low cost, strong adaptability, aging resistance, accurate commissioning, and no compensation error. It has high protection level, perfect protection performance, and high degree of automation. It is also suitable for on-site power distribution and control, and can be used as an auxiliary device for other power distribution equipment. It is an ideal product for power grid transformation. This product complies with GB7251.1 standard and has passed CQC certification. The reactive power compensation device has passed the test of the quality inspection and testing center, and all indicators meet the JB7113 standard for low-voltage parallel capacitor devices.
The ZW20-12 series outdoor pole-mounted intelligent high-voltage circuit breaker adopts a miniaturized spring operating mechanism design, making it more stable and reliable. The enclosure uses sealing, explosion-proof, and insulation technology, with good overall sealing performance. This product uses vacuum arc extinguishing and SF6 gas as the insulation medium, making it a maintenance-free, high-quality pole-mounted circuit breaker.
The ZW43-12 type outdoor high-voltage vacuum circuit breaker is a 12kV rated voltage, three-phase AC 50Hz outdoor power distribution equipment. It is suitable for use in substations and industrial and mining enterprise power distribution systems for protection and control, as well as in rural power grids with frequent operations. It can also be used as a ring network power supply unit and terminal equipment for power distribution, control, and protection of electrical equipment.
